摘要
在位置管理中，轨迹代表了一个运动物体在三维时空中的运动，即一个序列(x, y, t)。不幸的是，位置技术不能保证无误差。因此，地图匹配(又名捕捉)，将轨迹匹配到地图上的道路，是必要的。我们引入了一种基于权重的地图匹配方法，实验表明，在离线情况下，我们的算法在依赖GPS采样间隔的情况下，平均准确率可达94%。
A weight-based map matching method in moving objects databases
In location management, the trajectory represents the motion of a moving object in 3D space-time, i.e., a sequence (x, y, t). Unfortunately, location technologies, cannot guarantee error-freedom. Thus, map matching (a.k.a. snapping), matching a trajectory to the roads on the map, is necessary. We introduce a weight-based map matching method, and experimentally show that, for the offline situation, on average, our algorithm can get up to 94% correctness depending on the GPS sampling interval.
